im a newbe, i'm trying to get the username in a view

[Apolo Machine]

I'm trying to get the username within a view(CBV), the documentation I 
found says that the logged user is within the request, but when I do 

class ServiceCreateView(LoginRequiredMixin, CreateView):
          model = Service
          form_class = ServiceForm
          user=request.user.username 

i get this error 

AttributeError: module 'django.http.request' has no attribute 'user

any help is appreciated
